The path followed by a roller coaster as it climbs up and descends down from a peak can be modeled by a quadratic function, wher

Romashka [77]

Answer:

$y = -0.1x^2 + 250 ft$

Step-by-step explanation:

Because this quadratic equation would have the curve-down form of:

$y = -ax^2 + b$

where a and b are positive coefficient.

If we let the peak (250 ft) of the curve be at x = 0. Then

$y = -a0^2 + b = 250$

$b = 250$

Also at the begins and ends, thats where y = 0, the 2 points are separated by 100 ft. So let the begin at -50 ft and the end at 50ft. We have

$-a(\pm 50)^2 + 250 = 0$

$-a2500 = -250$

$a = 250/2500 = 0.1$

Therefore, the model quadratic equation of our path would be

$y = -0.1x^2 + 250 ft$
